To all whom it may concern.

Be it known that I, JAMES BAIwsLsY, a

citizen of the United States, residing at Akromin the county'of Summitand State ofOhio,'hav e invented new and useful ImprovementsimDevulcanizing Apparatus, of which thetollowing-is a specification.

Tl is invention relates to an apparatus for devu canizing ground rubberwaste or other articlds composed of ingredients having rubber as theprincipal part thereof, the object of the invention being to provide asimple, cheap and eflicient apparatus of this class whereby all of thewaste rubber is reclaimed, so that it may again'be'used' for any desiredpurpose.

With the above and other objects in view which will appear as thedescription progrosses, the invention resides in the novel construction,arrangement and combination of parts hereinafter fully described andclaimed. I

=1n the drawings,'Figure 1 is a side elevation of a device constructedin accordance with. the present invention. Fig. 2 is acentrallongitudinal section of the same. Fig. 3 is a transversesectional view taken upon the line 3-3 of Fig. 2. Fig. 4 is a similarsectional View taken upon the line 4+4 of Fig. 2.

- In the accompanying drawings, the numeral l designates a receptaclewhich is adapted to receive the ground rubber waste This receptacle ispreferand chemicals. ably circular in cross section and has its innerfaces lined with lead 2, or an analogous material which is notsusceptible to the corrosive activities of the chemicals within thereceptacle. I

{The receptacle 1 is centrally provided with two-or more manholeopenings having surrounding collars 3, and whereby'the rubber scraps to'be treated as well as the chemicals may be inserted within thereceptacle. The collars 3 are tightly closed through the medium ofremovable caps '1 the said caps as welljas the collars being providedwith a coating of non-corrosive material. and the jointfbetweenthe'collars and caps being of such an arrangement as to hermeticallyseal the openings of the receptacle.

The receptacle 1 has its. inner portion provided with a plurality ofspaced bafiiing plates, 5, the same being positioned longi tudinally ofthe said receptacle and having their offset or radiating portions formedwith teeth 6 at the edges thereof. The teeth 6 of one of the bafflingplates may be positioned to aline with the space between the teeth ofthe succeeding and preceding baffling plates, if desired, so that therubber beingtreated within the receptacle will be positively contactedby the teeth and the said rubber thus rendered more easily so1uble andthe composition formed with the rubbense arated.

The-co lars provided upon the openings forming the manhole are soarranged in relation to thereceptacle that the said receptacle will becounterbalanced thereby, and the collars 3 and caps 4 thus materiallyassisting in the rotation of the receptacle in a manner which willpresent-1y be set forth.

The receptacle 1 is provided at suitable spaced intervals with reliefvalves 7. These valves 7 are positioned a suitable distance adjacent theopenin s provided by the manholes and the said valves are protectedthrough the medium of suitable reticulated coverings designated by thenumeral 8. The said coverings are preferably of a rectangular formationhaving an open bot "tom, the sides and ends of each of the saidcoverings being reticulated as heretofore set forth and each ofthe saidcovers being constructed of some suitable material not susceptible tothe disintegrat-in effects of the chemicals within the receptac e. Thereceptacle is adapted for rotation and is centrally provided uponitsopposite ends with enlarged pipe members 9. Each of the said pipemembers is mounted in a suitable bearing 10, the said bearing beingpreferably provided with anti-frictional balls secured upon the pipes orhollow shafts 9, the said pulleys being connected through. the medium ofsuitable belting with a source of power and whereby the receptacle 1 maybe rotated. Each ct the hollow shafts 9 have their free ends @providedwith packing boxes 13 and l lik, l?ositioned within the hollow shaft, 9having the packing box 13 is a pipe member 15, the latter being providedwith a suitable valve 16, the purpose of which will be presentlyapparent.

Y The hollow shaft 9 provided with the connected with a water pipe 20. Te in- E jectorjgmty' be of any ordinary or preferred construction, andis provided with the usual operatln handle whereby the steam is allowedwithin the said injector to pass therefrom through the pipe 17 andhollow'shaft 9, to the race tacle -1-. The water pipe is provided-witth'e'usual valve 21 and the injector is' also provided with. an overflowpi e 22.

xtending' longitudinally within thereceptacle -1-1s a perforated'pipe23. This pipe has-one of its ends closed and its opposite end,communicating with passages provided by the hollow shaft 9, pipe 17 andinjector 18.; The closed end of the pipe 23 is retained in positionthrough the medium of a *suitablesupport 24, while the outlet providedby the hollowshaft connected with the pipe 15 is protected through themedium of areticulated member. 25. V

Briefly stated, the operation of the device is as follows :--The oundrubber is insorted through one o the manholes of the receptacle 1,together with a sutlicient amount of chemicals which are adaptedfi)assist. in the process of reclaiming the rubher from the compositionformed with the rubber, The valves are all closed. The cap .is re lacedup on the manhole and power is applied through the medium ofonenf thepulleys to rotate the receptacle 1. Thein- 'ector is then sets-so as toallow steam to passthroughthe pipe .19 and hollow shaft 9 into theperforated pipe 23'. The steam is ejected through the minuteperforations of the pipe 23 in'either direction, so that the radiatingsprays/contact the rubber pat tides and the chemicals. This process 18keptup. for a number; of hours and when sufficient time-has lapsed to,thoroughly soften the rubber to permit the partlcles comprising thecomposition to be removed therefrom, the steamfrom the injector isstopped and water is allowed to flow through the pipe 20 tothereticulated pipe 23. The injector is thenoperated so that the steam fromthe pipe. 19 will act upon the-water from the pipe 20 so as to force thesame. rapidly through the perforations.

After mingling the water andsteam with the chemicals-within thereceptacle for a suflicient length of time, the inflow of. waterandsteam-is cut a.; The lowermost valves v:7 are' then opened and theWallet is'per mitted an outlet. Afte'r"a1l the water has beenremovedfrom'the receptacle one of the capsAjs removed'from the'manhole'opening and the reclaimed rubber withdrawn froin the receptacle.- 7

It is tobevunderstood that the valve 416 connectedw'ithth pipe 15is'opened when valved outlets in said receptacle,

.on one plate ,tweenjthe teeth on the .low' shafts'carried by. saidreceptacle and the steam and water are allowed to enter the receptacle1, so that the base or composite material may find an outlet throughthis pipe 15, It is to be further understood that when steam alone isbeing injected within the receptacle 1, the valve 16 is closed, so

that the steam and chemicals are allowed a full and free act-ion uponthe rubber and composition.

Having thus fully described the invention, what I claim as new, is

1. A device of the class described comprising a cylindrical receptacle,a lining of non-corrosive material, diametrically opposite man-holes insaid receptacle, removable closures for saidman-holes, a plurality ofdiametrically opposite valved outlets for said receptacle, reticulatedprotectors for said. valved outlets carried by the non-corrosive lining,hollow shafts carried by said vreceptacle, supports for rotatablymounting said shafts, means whereby said shafts may be operated, areticulated protector carried bye-lining"from one of the shaft openings,a pipe mounted within the other hollow shaft and extending into thereceptacle, the inner portion of said pipe "being perforated and havingits end closed, and means by which jfiuid may be injected through saidpipe into communicatmg with its end openings,

which said shafts may be opmeans .by

era-ted, supports for rotatably mount-ing said shafts, a fixed pipemounted with. one of said shafts and extending into the receptacl'e, thenner portion of said pipe be ing enlarged, perforated, and. having itsendclosed, a fixed external support for said pipe, means ceptacle'through said perforated plpe, and means whereby the flow of liquid maybe regulated;
